I was thinking about it and I know of some electricians who happily commute three hours no traffic to certain jobsites to work 5 10's and pocket the per diem
Neat. Anecdotally I can confirm that as I work construction so have a variable commute. 30 minutes is fine, 45 an inconvenience, and an hour having me thinking about quitting.
Left is basic algebra/geometry that allows anyone to find a basic square angle. It's used daily in construction. You can learn how to use it today by searching "345 triangle"
As a side note, it's way easier for me to do this on mobile than on my instance via web.
